Lilen is one of the five mermaid sisters who were sought after by the Cray Trading Company for their skins. She escaped from the poachers coming for them on the Deserted Island by hiding in the waters near the island, and returning to wait for her sisters after the poachers left. Lazlo finds her, and upon being told that her sisters are safe on the ship she joins them, and works with them fabricating accessories in the atelier. After the war is over, she returns to the Deserted Island. She writes and speaks among the most clearly of the mermaid sisters. - KoRnholio
